Low Voltage General Purpose Transformers

UL Listed, CSA Certified Single Phase Type 1-E Encapsulated

UL Listed Three Phase Type 3-E Encapsulated

UL listed Single Phase Type 1-V Ventilated

UL Listed Three Phase Type 3-V Ventilated

Type 1-E general purpose transformers are single phase, resin encapsulated designs suitable for indoor or outdoor applications. It's totally enclosed, non-ventilated enclosure make it ideally suited for use in areas that contain dust, moisture, or corrosive fumes. Available in ratings through 25 KVA type 1-E transformers can be mounted in any position for indoor installations and in upright positions only for outdoor installations.

Type 3-E resin encapsulated, 3-phase transformers are available in ratings of 3-75 KVA. Its totally enclosed non-ventilated enclosure makes the 3-E ideally suited for outdoor as well as indoor locations. Type 3-E transformers utilize the 185°C insulation system with 115°C rise. 3-E transformers 3-15 KVA are T-T connected.

1-V general purpose transformers are single phase ventilated units designed primarily for indoor locations (also for outdoor , 600 volt class with the addition of weathershields). The 1-V utilizes a 220°C insulation system with 150°C rise and is available in ratings of 15-167 KVA.

The 3-phase 3-V ventilated dry-type is available in ratings of 15-750 KVA. Its 220°C insulation system (150°C rise) is self-extinguishing. 3-V enclosures are designed for indoor locations (or outdoor, 600 volt class with addition of weathershields).

Mounting Units installed outdoors must be mounted in upright position. Efficiency The Micron series of ventilated 600 volt class general purpose distribution transformers meet NEMA TP-1 efficiency

requirements and federal energy efficiency laws as mandated by the Energy Policy Act of 2005. Distribution

transformers installed in the United States are required to meet these energy efficiency requirements.

Winding Terminations

Primary and secondary windings are terminated in the wiring compartment. Encapsulated units have copper leads or

stabs brought out for connections. Micron recommends external cables be rated 90°C (sized at 75°C ampacity) for

encapsulated designs.

Series-Multiple Windings

Series-multiple windings consist of 2 similar coils in each winding which can be connected in series or parallel

(multiple). Transformers with series-multiple windings are designated with an "X" or"/" between the voltage ratings.

such as primary voltage of "120/240" or "240 X 480". If the series-multiple winding is designated by an "X" the winding

can be connected only for a series or parallel. With the"/" designation, a mid-point also becomes available in addition

to the series or parallel connection. As an example, a 120 X 240 winding can be connected for either 120 (parallel) or

240 (series), but a 120/240 winding can be connected for 120 (parallel), or 240 (series), or 240 with a 120 mid-point.



General Information Industry Standards All Micron dry-type distribution and control transformers are built and tested in accordance with applicable NEMA, ANSI and IEEE standards. All 600 volt class transformers are UL listed unless otherwise noted.

Seismic Qualified The Micron family of dry-type distribution transformers is seismically tested, seismically qualified, and exceeds requirements of the Uniform Building Code (UBC) and California Code Title 24.

Frequency Micron standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies must be specifically designed.

Overload Capability Short term overload is designed into transformers as required by ANSI. Basically, dry-type distribution transformers will deliver 200% nameplate load for one-half hour; 150% load for one-hour; and 125% load for four-hours without being damaged provided that a constant 50% load precedes and follows the overload. See ANSI C57 .96-01.250 for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading.

Insulation System & Temperature Rise Industry standards classify insulation systems and rise as shown below:

The design life of transformers having different insulation systems is the same – the lower temperature systems are designed for the same life as the higher temperature systems.

Selection Guide for Single Phase Transformers

Single Phase AC Motors₁ 1. Determine the primary (source) voltage

-the voltage presently available.

2. Determine the secondary (load) voltage

-the voltage needed at the load. 3. Determine the Kva load: If the load is defined in Kva, a transformer

can be selected from the tabulated data.

If the load rating is given in amperes,

determine the load Kva from the Full Load

Current chart. To determine Kva when volts

and amperes are known, use the formula:

Kva = Volts x Amperes

1000 If the load is an AC motor, determine the

minimum transformer Kva from the chart at the right.

Select a transformer rating equal to or greater than the load Kva.

4. Define tap arrangements needed. 5. Define temperature rise. Using the above procedure, select the transformer from the listings in this catalog.

BUCK-BOOST TRANSFORMERS

Single and Three Phase Applications – 60Hz

A Buck-Boost Transformer is used to provide an economical method of correcting a lower or higher voltage to a

voltage rating more suitable for efficient operation of electrical equipment.

Buck-Boost Transformers are small Kva, single phase, 600 volt class insulating transformers with dual primary and dual

secondary windings. If wired as an isolation transformer, they can be utilized to provide for applications requiring 12,

16, 24, 32 or 48 Vac up through 7.5Kva. However, they are usually connected as autotransformers by utilizing one unit

for single phase applications and either two or three units banked for three phase operation. They are primarily used

for motor operation and should not be used for motor control circuits, to correct fluctuating line voltage or to obtain a

neutral on a delta system. These applications require transformers especially designed for these specific applications.

NOTE: When installation is to be made on a grounded system, consideration must be given to the resulting voltage.

Thus, on a 208 grounded wye/120 system the voltage can be boosted to 240 volts but the voltage to ground will be

139 volts. If 240/120 volts with a midpoint ground is needed, a standard two-winding transformer must be used.

The following formula can be used to calculate specific requirements.

For Single Phase For Three Phase

LOAD KVA= LOAD KVA=

Load Voltage x Full Load Amps Load Voltage x Full Load Amps x 1.732

1000 1000

For quick selection data, refer to the tables on the following pages.

Selection Requirements Selection Information

First, you should have this information before selecting

a buck-boost transformer.

Line Voltage- The voltage that you want to buck

(decrease) or boost (increase). This can be found by

measuring the supply line voltage with a voltmeter.

Load Voltage- The voltage at which your equipment is

designed to operate. This is listed on the nameplate of

the equipment.

Load Amps or Load Kva- You do not need to know both

– one or the other is sufficient for selection purposes.

This information usually can be found on the

nameplate of the equipment that you want to operate.

Frequency- The supply line frequency must be the

same as the frequency of the equipment being

operated. Micron Buck-Boost transformers operate at

60 Hertz only.

Phase- The supply line should be the same as the

equipment to be operated – either single or three

phase.

Transformer Interconnection

For three phase applications, interconnections of

transformers should be made in a junction box. Two or

three transformers may be used depending on an open

delta (2) or wye (3) connection.

5-Step Selector

The tables which follow will simplify the selection of

the buck-boost transformers. There are no calculations

needed; simply follow these 5 steps.

1. Refer to the table having the same output voltage as

the equipment that you want to operate. For example,

if you are installing a 240 volt, 6Kva single phase load,

use Selection Table Number 4.

2. Select the available line voltage across the top of the

chart which is closest to the actual supply voltage. In

the example, if the available line voltage is 213 volts,

use the 212 volt Column.

3. Read down the column until you reach an output

Kva or amps rating equal to or greater than the load

requirements. Since 6Kva, in the example, is not listed,

use the next higher rating or 7.5Kva.

4. Read across to the far left columns for the catalog

number and quantity of transformers for your

application. In the example, you will need (1) catalog

number J001K1EB1A02.

5. Connect the selected buck-boost transformer(s) in

accordance with the connection diagram specified at

the bottom of the “Available Voltage” column. In the

example, Diagram “F” would be used.

NOTE: For 1 phase connections and 3 phase open delta

connections, inputs and outputs may be reversed. Kva

capacity remains constant.

Transformer Accessories Wall Mounting Brackets are used to wall mount most

15 through 75Kva and some 100 and 112.5Kva Type

1-V and 3-V transformers. this bracket allows for 6”

Clearance from the wall as recommended by Micron.

A Weathershield Kit consisting of a front and rear cover shield must be installed on all ventilated dry-type

transformers when the unit is located outdoors. The shields

protect the transformer top ventilation openings against rain

but allow for proper ventilation. Field installation hardware

is not required. Proper installation provides a NEMA 3R

rating.

Refer to the specific transformer listing for selection of the

proper kit.

What is an LVGP Transformer: Transformers are AC to AC devices. You cannot transform DC Enclosed Power Transformers can be either single or three phase. They are also called "LVGPs" or "Dry Types". These are always in a potted or ventilated enclosure. TERMS: Sinusoidal: Or sine wave. A mathematical function that describes a smooth repetitive oscillation. The phase is defined where in the cycle the oscillation begins. See following depiction.



Three Phase: The common method of electrical power generation and transmission. The generator at the power station converts mechanical power into a set of alternating electrical currents, one from each electromagnetic coil or winding of the generator. The currents are sinusoidal functions of time, all at the same frequency but with different phases. The phases are equally spaced and separated from each other by 120 degrees. 3 cycles 120° apart = 360° or one revolution of the generator. It is the revolving magnetic field caused by the three phases that causes an electric motor to start turning.

2-Pole/Phase Three Phase Motor

Single Phase: Single phase power is produced from a three phase source by connecting either between a phase and neutral or connecting phase-to-phase. Interestingly, single phase cannot produce necessary revolving magnetic field to start an electric motor turning. All single phase motors need additional circuits for starting. A single-phase sine wave is depicted as is a 2-Pole Single-Phase motor. as opposed to the rotating field produced by three phase, the single phase fields merely oscillates. Once rotation begins the momentum of the rotor allows rotation through the "dead areas". A phase-leading current is necessary to begin rotation and is developed by the added resistance of a start winding or by a capacitor.

Neutral: The neutral is the point on a three phase system where each of the phase points are equal in magnitude and equally spaced in phase. It is the mathematical center of an equilateral triangle formed by the three phase points. Because of this, the phase-to-phase voltage is √3 (1.732) times the phase-to-neutral voltage. Example: 120V phase-to-neutral X 1.732 = 208V phase-to-phase. G015K5QH2A04 has a secondary of 208Y/120 The neutral allows the balancing of single phase loads between any/all of the individual three phase legs and the neutral point while still allowing for normal three phase loading. The neutral is also a grounded conductor which typically ties to the system's earth ground at the breaker panel. FCAN/FCBN: An acronym for Full Capacity Above Normal and Full Capacity Below Normal. These are taps on the primary side to adjust for slightly low or high line voltage. Expressed in % of adjustment. Example: FCAN: 2 @ +2.5% / FCBN: 4 @ -2.5%



Phase-to-Phase: Voltage measured between any two "corners" of a Delta connection or between any two "legs" of a Wye connection. Wye: Also called “Star”. All phase windings are connected at a common point (resembles a star) which is typically where a fourth wire (neutral) and a ground is connected. Three phase loads are connected to the “A”, “B” and “C” (line-to-line) terminations while single phase loads are typically connected line-to-neutral. Unless they are light, connecting single phase loads line-to-line unevenly loads two windings, may unbalance the phases and derates the transformer more than connecting line-to-neutral.

Delta: A common three-wire, three phase system in which the voltage potential between each pair of wires is the actual transformer voltage. Although typically ungrounded, a “grounded reference” can be developed by center-tapping the “A”-“C” winding (see High Leg) allowing for more load flexibility. High Leg: Also called a “Wild Leg” or “Stinger”. On a three phase Delta system, a mid-point or center tap of the “A” to “C” phase winding is labeled “N” and becomes a grounded reference (sometimes referenced to as neutral). Voltage measurements between possible connection points on the above diagram are as follows: Phase-to-Phase Phase-to-Neutral “A”-“B” = 240V “A”-“N” = 120V (240/2) “B”-“C” = 240V “B”-“N” = 208V (240/2 X √₃) “C”-“A” = 240V “C”-“N” = 120V (240/2)

High Leg Delta systems provide increased voltage flexibility over similar Wye systems because, in addition to a ground and 120 volt single phase, they offer a higher (240V) three phase connection. The disadvantage is that no single phase 120 volt load can be connected to the “B” leg and this may unbalance the total load. Open Delta: A three phase transformer bank using two transformers. Although one side of the Delta is physically not there, an electrical measurement is possible across the missing side (diagram below)

An Open Delta is not as efficient as a three transformer system and is normally reserved for smaller loads. An Open Delta is capable of 57.7% of a true Delta load. Many three phase buck-boost applications are wired in Open Delta configuration.
